PIPE-WRENCH.

Specification of Letters Patent.

Patented Sept. 2.2, 1919.

Application led April 26, 1919. Serial No. 292,774.

To all 'whom t may concern Be it known that I, JAMES A. JONES, a citizen of the United States, residing at Logansport, in the county of Cass and State of Indiana, have invented anew and useful Pipe-Vrench, of which the following is a specification.

The present invention relates to pipe wrenches and has as its object to provide a pipe wrench which consists mainly of a single bar of metal bent to provide the pipe gripping jaws which will grip the pipe 1n vise-like fashion.

A further object of the invention is to provide a wrench which is not to possess any complicated parts which are likely to become inoperative but which is on the contrary a device of durability and simplicity.

A further object of the invention is to provide a pipe wrench which embodies removable gripping plates that may be readily detached from the jaws of the wrench when they become worn and new ones readily inserted in the jaws.

Another object of the present invention, is to provide a wrench which has a positive gripping action and which is formed from a single length of material.

An additional object is to provide a device having the above characteristics which is simple in construction, which consists of few parts, and which may be manufactured and marketed at a minimum cost.

With the above and other general objects and advantages in mind, the invention consists of combinations of elements, arrangements of parts, formations and general assemblage which will be hereinafter fully set forth and illustrated in the accompanying drawings, the invented features of the device being explicitly defined in the subjoined claims.

On the drawings:

Figure 1 is a side elevation of a wrench constructed as contemplated by the invention;

Fig. 2 is a transverse sectional View taken on line 2--2 of Fig. 1; and

Fig. 3 is also a transverse sectional view taken on line 3-3 of Fig. 1.

Referring in detail to the drawing wherein like characters of reference denote like parts on all of the views the numeral 5 denotes a bar'of stout metal which may be of rectangular formation in cross section. The major portion of the length of metal conJ stitutes a shank G having a handle 7 formed at one end thereof and its opposite end constituting a gripping jaw.

The opposite end of the bar metal 5 is bent at 8 and extended obliquely with respect to the longitudinal axis of the major portion of the bar toward the handle 7. This latter portion constitutes a gripping jaw 9, is opposed to the jaw formed with the shank 6 and coperates with the same. Opposed dovetailed recesses 10 are formed 1n the opposite faces of the gripping jaws in which are removably mounted serrated plates 1l, the recesses 10 being formed contiguous with each other and the inner ends of the plates 11 being beveled and arranged 1n abutting relation. Set screws 13 secure the outer ends of these plates 11 in the recesses while their opposite ends are held against movement 'by plates 14; arranged upon opposite sides of the jaws at their juncture and overlap the inner edges of the plates. If desired one of the plates 11 may be omitted.

From this disclosure it will be apparent that I have provided a positive gripping wrench, the operation of which is obvious. It will also be apparent that the plates ll may be removed by disengaging the plates 14 and the set screws 13 from the device in order to replace the same with new ones.

This embodiment of the invention is considered the preferred construction but it is to be understood that the same may be modified in many respects, and that my limits of such modification are only governed by what is claimed.

What is claimed is 1. In a wrench, a bar of metal, the intermediate part of the metal constituting a grippmg jaw, a handle formed at one end of the length of metal, a second gripping jaw extending obliquely of the outer end of the first-mentioned jaw and in opposed re lation to the same, each of the jaws being provided with opposed recesses, serrated gripping plates mounted in the recesses, set screws extending through the outer ends of the plates and jaws, and detachable plates secured to the jaws at their juncture and projecting beyond the inner edges of the gripping plates to retain the same in position.

2. The combination with a wrench having a pair of opposed gripping jaws one of which extends obliquely with respect to the other and each having a recess in its oppose/d In testimony that I claim the `foregoing face, a serrated plate arranged in each reas my own, I have hereto afxed my signa- 10p eerbss and having its inner ends disposed in ture in the presence of tWo Witnesses. a utting relation and a plate detaehably mounted upon each yside of the jaws and ',jAMEb A JONES overlying the abutting en'ds of the serrated Witnesses:

plates to retain the same in position in the l WM. MALEAGH, recesses. l MARY PIERCY.
